Problems with The Jacobians

Stochastic simulations
1

Hello everyone,
When I run my model, it stops with the following error message:
there is 1 colinear relationships between the variables and the equations
Colinear variables:
c
n
b
y
Colinear equations
2 8

I would appreciate if someone could remind me any way to sovle the colinear relationships
Thank you very much in advance.

You have tau=0 in steady state, so

psi*exp(n)^(thetta) = (1-exp(tau))*exp(w)*UC;

will have a 0 on the right.
